• The drain pipe must be installed as shown in the diagram (see diagram above) to avoid damage caused by leaks and

condensation.

• For the best result, keep the piping as short as possible. Slant the piping at an angle to improve the ﬂ ow.

• Ensure the drain pipe is securely insulated.

• It is necessary to provide a drain trap in the drain outlet to relieve pressure that exists within the unit compared to the outside

atmospheric pressure when the unit is operating. The drain trap is to avoid possibility of splashes or an odor.

• Keep pipes as straight as possible for easy cleaning and to prevent the accumulation of dirt and debris.

• Conduct a water drainage test after the installation is completed. Make sure that the drainage ﬂ ow is smooth.

• In humid environments, use an extra drain pan to cover the entire area of the indoor unit.

Piping Works And Flaring Technique

Do not use contaminated or damaged copper tubing. If any

piping, evaporator or condenser had been exposed or had

been opened for 15 seconds or more, the system must be

vacuumed. Generally, do not remove plastic, rubber plugs

and brass nuts from the valves, ﬁ ttings, tubings and coils

until it is ready for connection.

If any brazing work is required, ensure that the nitrogen

gas is passed through piping and joints while the brazing

work is being done. This will eliminate soot formation on

the inside walls of the copper tubings.

Cut the pipe stage by stage, advancing the blade of pipe

cutter slowly. Extra force and deep cut will cause more

distortion of pipe and therefore extra burr. See Fig. A

Remove burrs from cut edges of pipes with a remover as

shown in Fig. B. This will avoid unevenness on the ﬂ are

faces which will cause gas leak. Hold the pipe on top

position and burr remover at lower position to prevent metal

chips from entering the pipe.

•

1/4t

Cutting Copper Tube

Insert the ﬂ are nuts mounted on the connection parts of both

indoor and outdoor unit, into the copper pipes.

The exact length of pipe protruding from the face of the

swaging block is determined by the ﬂ aring tool. See Fig. C

Fix the pipe ﬁ rmly on the swaging block. Match the centers

of both the ﬂ are die and the ﬂ aring punch, and tighten ﬂ aring

punch fully.

Piping Connection To The Units

Align the center of the piping and sufﬁ ciently tighten the

ﬂ are nut with ﬁ ngers. See Fig. D

Finally, tighten the ﬂ are nut with torque wrench until the

wrench clicks.

When tightening the ﬂ are nut with the torque wrench,

ensure that the direction for tightening follows the arrow

on the wrench.

The refrigerant pipe connection are insulated by closed cell

polyurethane.

SPECIAL PRECAUTIONS WHEN DEALING WITH R410A UNIT

Attach insulation sleeve

Round crimp-style terminal

Electric wire

• All wires must be ﬁ rmly connected.

• Make sure all the wire do not touch the refrigerant pipings, compressor or any moving parts.

• The connecting wire between the indoor unit and the outdoor unit must be clamped by using provided cord anchorage.

• The power supply cord must be equivalent to H07RN-F which is the minimum requirement.

• Make sure no external pressure is applied to the terminal connectors and wires.

• Make sure all the covers are properly ﬁ xed to avoid any gap.

• Use round crimp-style terminal for connecting wires to the power supply terminal block. Connect the wires by matching to

the indication on terminal block. (Refer to the wiring diagram attached on the unit).

Connect wires of the

same gauge to both side.

Do not connect wires of the

same gauge to one side.

Do not connect wires

of different gauges.

R410A is a new HFC refrigerant which does not damage the

ozone layer. The working pressure of this new refrigerant is

1.6 times higher than conventional refrigerant (R22), thus

proper installation / servicing is essential.

• Never use refrigerant other than R410A in an air conditioner

which is designed to operate with R410A.

• POE or PVE oil is used as lubricant for R410A compressor,

which is different from the mineral oil used for R22

compressor. During installation or servicing, extra precaution

must be taken not to expose the R410A system too long

to moist air. Residual POE or PVE oil in the piping and

components can absorb moisture from the air.

• To prevent mischarging, the diameter of the service port on

the ﬂ are valve is different from that of R22.

• Use tools and materials exclusively for refrigerant R410A.

Tools exclusively for R410A are manifold valve, charging

hose, pressure gauge, gas leak detector, ﬂ are tools, torque

wrench, vacuum pump and refrigerant cylinder.

• As an R410A air conditioner incurs higher pressure than

R22 units, it is essential to choose the copper pipes correctly.

Never use copper pipes thinner than 0.8mm even though

they are available in the market.

• If the refrigerant gas leakage occurs during installation /

servicing, be sure to ventilate fully. If the refrigerant gas

comes into contact with ﬁ re, a poisonous gas may occur.

• When installing or removing an air conditioner, do not allow

air or moisture to remain in the refrigerant cycle.

• Used the correct screwdriver for terminal screws tightening. Unsuitable screwdrivers can damage the screw head.

• Over tightening can damage the terminal screws.

• Do not connect wire of different gauge to same terminal.

• Keep wiring in an orderly manner. Prevent the wiring from obstructing other parts and the terminal box cover.

VACUUMING AND CHARGING

Vacuuming is necessary to eliminate all moisture and air from the system. The series II Outdoor Unit is provided with ﬂ are

valve ﬁ ttings.

Vacuuming The Piping And The Indoor Unit

Except for the outdoor unit which is pre-charged with

refrigerant, the indoor unit and the refrigerant connection

pipes must be air-purged because the air containing moisture

that remains in the refrigerant cycle may cause malfunction

of the compressor.

• Remove the caps from the valve and the service port.

• Connect the center of the charging gauge to the vacuum

pump.

• Connect the charging gauge to the service port of the 3-way

valve.

• Start the vacuum pump. Evacuate for approximately 30

minutes. The evacuation time varies with different vacuum

pump capacity. Conﬁ rm that the charging gauge needle has

moved towards -760mmHg.

Caution

• If the gauge needle does not move to -760mmHg, be sure to

check for gas leaks (using the refrigerant detector) at ﬂ are

type connection of the indoor and outdoor unit and repair

the leak before proceeding to the next step.

• Close the valve of the changing gauge and stop the vacuum

pump.

• On the outdoor unit, open the suction valve (3 way) and

liquid valve (2 way) (in anti-clockwise direction) with 4mm

key for hexagon sacked screw.

Charge Operation

This operation must be done by using a gas cylinder and a

precise weighing machine. The additional charge is topped-up

into the outdoor unit using the suction valve via the service

port.

• Remove the service port cap.

• Connect the low pressure side of the charging gauge to the

suction service port center of the cylinder tank and close

the high pressure side of the gauge. Purge the air from the

service hose.

• Start the air conditioner unit.

• Open the gas cylinder and low pressure charging valve.

• When the required refrigerant quantity is pumped into

the unit, close the low pressure side and the gas cylinder

valve.

• Disconnect the service hose from service port. Put back the

service port cap.

As shown in ﬁ gure above, it is recommended to move the unit

by grabbing the left and right grip. Place your hands on the

corner to avoid deforming of the casing.

Figure 1

A total of 4 direction options (refer ﬁ gure 2a) for connecting

pipe (w, x, y, z) are available for your convenience.

Cutting out the 2 slits with a metal saw make it possible to

install as shown in ﬁ gures 2a.

In order to make the connecting pipe in a downward direction

(refer ﬁ gure 2b), make a knockout hole by drilling through

the center area around the knockout hole.

It is recommended to use a Ø6mm drill for this process

(refer ﬁ gure 2c).

After completing the knockout process, it is recommended

to apply repair paint to the edge and surrounding surfaces to

prevent rusting.

1. Handling

2. Refrigerant piping

Cover the pipe through-holes with insulation material to

conceal all gaps to prevent small animals or insects from

entering the outdoor unit which may result short circuit in

the control box.

4. Charging refrigerant

For cases where complete recharge of refrigerant is required,

vacuuming via service part is mandatory, do not use stop valve

port in this case because vacuuming through this stop valve

port can not be executed completely.

Outdoor units have 1 port on the piping. It is between the heat

exchanger and the 4-way valve.

5. Pump-down operation

Never by-pass the low pressure switch or low pressure sensor

during pump down operation.

Power supply must be cut off before pump-down operation.

After opening the front panel, cover the PCB and terminal

board with insulation sheet to avoid electric shock by

accidental touching of LIVE parts.

Do not leave the unit unattended if the front panel is open.

Close the front panel before leaving the outdoor unit.

Turn on the power supply and carry out pumping-down

operation according to the steps written at front panel.

6. Electrical wiring work

Figure 4

Secure the ground wire to the stop valve attachment plate

(refer ﬁ gure 4) so that it does not slide.

Ensure the front cover does not rise up after the wiring work

is down. Close the front cover securely.

3. Caution for handling service port

To be able to recover all remaining

refrigerant at charge hose, always use

a ﬂ exible charge hose with a push-rod

and valve.

After the work, tighten the valve

cover in place with tightening torque:
